HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 144, 377, 473 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 144, 377, 473 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 144, 377, 473 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 144, 377, 473 is 1.

HCF(144, 377, 473) = 1

Highest Common Factor of 144,377,473 using Euclid's algorithm

Highest Common Factor of 144,377,473 is 1

Step 1: Since 377 > 144, we apply the division lemma to 377 and 144, to get

377 = 144 x 2 + 89

Step 2: Since the reminder 144 ≠ 0, we apply division lemma to 89 and 144, to get

144 = 89 x 1 + 55

Step 3: We consider the new divisor 89 and the new remainder 55, and apply the division lemma to get

89 = 55 x 1 + 34

We consider the new divisor 55 and the new remainder 34,and apply the division lemma to get

55 = 34 x 1 + 21

We consider the new divisor 34 and the new remainder 21,and apply the division lemma to get

34 = 21 x 1 + 13

We consider the new divisor 21 and the new remainder 13,and apply the division lemma to get

21 = 13 x 1 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 144 and 377 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(34,21) = HCF(55,34) = HCF(89,55) = HCF(144,89) = HCF(377,144) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 473 > 1, we apply the division lemma to 473 and 1, to get

473 = 1 x 473 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 473 is 1

Notice that 1 = HCF(473,1) .
